Shorod, found this good article on these systems. Good info and I have a better understanding on how and why this implementation has been created. Makes complete sense, in theory it should make batteries last longer. In my case it was my own fault. It only lasted a little over a 2yr 1/4 span. I've read many times how people wonder why their batteries last only 2 years. Improper charging after jump starts. I recall on my battery, right before it almost didn't crank after shutting it down, a voltage of 10.9. And that's after reading 12.7v on a 15 minute trip. When the system was at a economy charge [12.7], it was just not enough for a tired abused battery. What's interesting, the ECU didn't bother sending a code to trigger the check engine light. Probable the programming parameters. But here's the link.
